Myra Thomas began her career in finance, eventually becoming AVP for a Lloyd’s of London intermediary. That background lends itself well to covering the gamut of tech and business news stories. During her 20-year journalism career, she’s served as an editor, reporter, author, researcher, and adjunct English lecturer. She lives in Northern New Jersey with her husband, two daughters, and two wily Cairn Terriers.

Courtesy of its IPO, Twitter has turned employees into millionaires, so most are undoubtedly more than happy with the company. Employees rate it 4.5 out of 5 stars and the bulk of its staff – 85 percent to be exact — would recommend working there to a friend, according to Glassdoor.

Still, despite the good times all around, Twitter employees say the environment isn’t perfect and employees are beginning to complain about the company’s shortcomings, says Business Insider. The majority of the complaints are related to the company’s fast growth. Among the 89 reviews on Glassdoor, employees posted:

“With growth comes some minor growing pains as more people fit into the organization.”

“Starting to feel like a big company, losing the startup feel.”

“You may find yourself hindered by confusing internal tools that aren’t managed well or well-documented.”

“Distributed office [workers] can sometimes feel disconnected from the HQ in San Francisco.”

Lots of engineering managers for a company of this size. Most of the engineering managers are non-technical and add little value (but do create a lot of noise). Alarming amount of internal politics for a company so small (of ~2000 people)! Feels like a company with 10x the number of people.

Meanwhile, a data scientist posted, “Manager inflation, and hierarchy, unfair and very non-uniform compensation.” A software engineer added: “Hiring has been heavy, but where the new workers fit into the picture is somewhat of a mystery in many groups.”

Others have a more positive spin on the company’s growing pains. One employee said, “Despite growing 10x in my time here, I actually feel that our talent level has increased from the early days. We are able to attract the best talent in engineering, sales, sales marketing, comms, legal, BizDev and finance.” A software engineer wrote, “Great CEO. Very transparent and genuinely cares about the company. Very smart people.” And an engineering manager posted, “Twitter is an exciting place to work. Hyper growth means there is a lot of opportunity to take on more responsibility.”
